DEVICE FOR IGNITION SYSTEM.

Application filed March 2, 1925.

This invention relates to a device for use in connection with ignition systems of internal combustion engines and more particularly to these or" Ford cars.

The object 01' the invention is to provide a simple and eilicient device of this character which operates to automatically clean the spark plugs.

Another object of the invention is to pro vide a device of this character constructed to insure smooth running oi the motor, to provide maximum pep with a minimum consumption of gas,

Another object is to provide a device of this character which is extremely simple in construction and may be readily applied to the primary terminals of the coils and is designed to cause a short circuit of these coils and to produce a spark at the plug at the moment the exhaust stroke is completed as well as the completion of the power stroke thus causing the plug to iire at every revolution of the motor and by means of which the oil accumulated on the plug is burnt oii' and the plug prepared for a cleaner and better explosion on the beginning of the power stroke.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings Figure 1 represents a front elevation of a dash board of a Ford car showing this im proved attachment applied; and

Fig. 2 is a detail sectional view taken on the line 2-2 of Fig. 1.

The device constituting this invention comprises two metal wires or strips 1 and 10 of different lengths, the strip 1 being of a length sullicient to span the space between the two terminals of the outer low tension coils shown at 2 and 8 The shorter wire 10 is of a length to span the distance be tween the two inner primary coil terminals 6i and 5. These wires 1 and 10 may be con- Serial No. 12,740.

nected with these terminals in any desired manner, preferably being connected by mounting them on a non-conductive strip or plate 15 which is equipped with tour apertures spaced to lit over the low tension terminals of the coils as shown in Fig. 2 and which are here shown equipped with metal eyes 16 arranged in the openings which fit over the coil terminals, these eyes providing attaching means for the metal wires or strips 1 and 10. The ends of these members 1 and 10 are here shown wound around the metal eyes 16 to form an electrical connection between the wires and the terminal coils when the device is applied.

W hen this device is applied as shown in Fig. 1 the wire or strip 1 operates to short circuit the two outer coil terminals 2 and 3 while strip 10 operates to short circuit the inner coil terminals a and 5. This short circuiting ot the coil terminals produces a spark at the spark plug at the end of each exhaust stroke of the motor as well as at the beginning of the power stroke. This insures the firing of the plug at every revolution of the motor instead of every second revolution. This firing however causes no explosion at the end of the exhaust stroke since there is no compressed gas to lire at that time and consequently the spark merely operates to burn oif the accumulated oil from the plug and prepares the plug for a cleaner and better explosion on the next power stroke.

This cleaning of the spark plugs at every stroke of the piston causes the motor to run more smoothly and with more pep with a minimum consumption of gas. This performance of the motor is made possible by the improved condition existing around the plug at the time of the vital explosion or at the beginning of the power stroke.

The device is simple and may be readily applied to any Ford car by an inexperienced person. all that is necessary being to remove the nut 6 from the coil terminals and apply the plate or strip 15 which carries the short circuiting wires 1 and 10. Then replace the nuts and the device will operate automatically.

This device is not to be confused with spark intensifiers which are applied to the high tension coils and which operate entirely different from this,

I olaim: v A device of the class described comprising 5 a strip'of non-conductive material having a plurality of apertures arranged therein to fit over the low tension terminals of the ignition system coil box and metal strips of a length to span the distance from the two outermost terminals and the two innermost v10 respectively and equipped with means for connecting them to said terminals.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature.

HENRY'I. RICHARDSON.
